Watching as the cursed form retreated into his body and he fell, Sakura realized this was what he had left them for, for all these years. This was the main cause for his leave. He grew stronger through this curse, became a different person with a crazy outlook on an even crazier dream. Even though Sasuke was on speaking terms with her now, (though she figured he didn't have much choice in the matter) she felt resentment toward that part of him.
She leaned down slightly to offer him a hand to stand back up while mulling over his offer. "A partial shift would be fine as long as I have the right area to focus on. As for the length... probably a few hours. Maybe three at best, I'm not sure. I've never worked with this curse seal before." She frowned. "I'm not going to lie... I am taking a risk by accepting but I am willing to do my very best with all the knowledge I already have. Give me a day or two to plan it out, okay?"
Well, this was certainly nervewracking. What if she messed up? What if she only made it worse on him? He'd think she was a joke or was trying to sabotage him. Then it was decided. She had to make this successful no matter what. How? ... She would figure that out later.
